Fault Alarm: Mainboard displays Fault E35: Elevator did not perform shaft self-learning, shaft self-learning conditions were not met, or shaft self-learning failed.
Fault Causes and Solutions:
i. Subcode 101: Self-learning not started at the bottom floor. The current floor is not the lowest floor or the forced deceleration of the next floor is ineffective. Ensure the forced deceleration of the next floor is effective and the lower limit switch + current floor is the bottom floor.
ii. Subcode 102: Inspection switch disconnected during self-learning.
Check the wiring of the inspection or emergency electric signal according to the schematic diagram to ensure the wiring is correct.
iii. Subcode 103: Power-on judgment indicates no shaft self-learning. This fault will be displayed when there is no shaft self-learning data in the mainboard. Before high-speed commissioning, this is a normal warning fault and will be cleared after performing shaft self-learning.
iv. Subcode 104: In distance mode, it is judged that shaft self-learning has not been performed during startup.
Re-perform shaft self-learning.
v. Subcode 105: Elevator running direction and pulse change direction are inconsistent.
It is necessary to confirm whether the change in elevator running direction is consistent with the pulse change of F4-03: When the elevator goes up, F4-03 increases; when the elevator goes down, F4-03 decreases.
vi. Subcode 106: Abnormal length of the insertion plate sensed at the upper level;
vii. Subcode 107: Abnormal length of the insertion plate sensed at the lower level;
viii. Subcode 109: Magnetic plate sensor length is too long.
1. Check F5 group: 01/33 Upper level normally open/normally closed
02/34 Lower level normally open/normally closed
03/35 Door zone normally open/normally closed
2. F6-00, F6-01 Top floor and bottom floor settings;
3. Check the length of the magnetic plate.
Set F6-00 and F6-01 according to the number of plug-in boards. If the above troubleshooting is fine, try setting F6-52 bit13=1. The leveling sensor's normally open/normally closed setting is incorrect. The leveling sensor signal is flickering; please check if the plug-in boards are installed correctly and check for strong electrical interference.
How to set the leveling sensor parameters?
The leveling signal consists of the leveling switch and the leveling plug-in boards, which are directly connected to the controller's input terminals. Their function is to ensure the car accurately stops at each floor. The leveling plug-in boards are installed on the guide rails in the hoistway. One leveling plug-in board is installed for each floor. Ensure that the length and verticality of the magnetic shielding board are consistent on each floor. The number of plug-in boards is the number of floors [(F6-00) - (F6-01) + 1].
ix. Subcodes 108 and 110: The self-learning leveling signal shows no change after 45 seconds. The leveling signal has not been received after the set time of FA-38+10 seconds.
1. Confirm the leveling sensor parameters are set correctly;
2. Set one sensor to the door zone;
3. Set two sensors to upper and lower leveling signals;
4. Check if the self-learning speed F3-26 is set too low;
5. Check if the leveling sensor wiring is normal;
6. Check if the floor spacing is too large, causing timeout. Increase the shaft self-learning speed and re-perform shaft self-learning so that the elevator can learn the longest floor within 45 seconds.
x. Subcodes 111 and 115: The learned or stored floor height is less than 50cm.
1. If there are floors with a height less than 50cm, the ultra-short floor function needs to be activated;
2. If not, check the installation of the plug plate for this floor, or check if the sensor and its wiring are normal.
xi. Subcode 112: After self-learning, if the current floor is not the highest floor, the highest floor is not the floor set by F6-00, or the maximum floor setting of F6-00 is incorrect, or the leveling plate is missing.
1. Check if the F6-00 setting is correct;
2. Check if the magnetic shielding plate is improperly installed. During self-learning, monitor F4-01 to see if the current floor is incremented by 1 after each floor passed.
xii. Subcodes 113 and 114: In distance mode, if self-learning of the shaft is not performed during startup, perform shaft self-learning again.
xiii. Subcode 116: In communication mode, the normally open/normally closed settings of the upper and lower leveling signals connected to the car top plate are incorrect.
1. Check if the leveling sensor signal is malfunctioning;
2. Check if the upper and lower leveling wiring is correct;
3. Check if the upper and lower leveling gap is reasonable;
4. In communication mode, check the opening and closing point settings of bit 9 and bit 10 of the leveling sensor on F5-25.
xiv. Subcode 117: The pulse length of the plug-in sensor detected by the communication leveling unit is abnormal, exceeding 655351.
1. The normally open/normally closed setting of the leveling sensor is incorrect (F525's normally open/normally closed setting for communication leveling signals);
2. The leveling sensor signal is flickering. Please check if the plug-in is installed correctly and check for strong electrical interference.
xv. Subcode 118: Communication leveling, upper leveling and upper-second leveling are reversed.
1. Check if the wiring of the upper leveling and upper-second leveling is correct;
2. Check if the gap between the upper leveling and upper-second leveling is reasonable;
3. The leveling signal is in communication mode. Check the on/off point settings of bit 9 and bit 10 of the F5-25 leveling sensor.
xvi. Subcode 119: Communication leveling, lower leveling and lower sub-leveling reversed.
1. Check if the wiring of the lower leveling and lower sub-leveling is correct;
2. Check if the gap between the lower leveling and lower sub-leveling is reasonable;
3. When the leveling signal is in communication mode, check the on/off point setting of bit 10 of the leveling sensor on F5-25;
xvii. Subcode 120: The difference in the length of the magnetic shielding plate learned by the upper and lower leveling layers exceeds 5cm. Check if the leveling sensor is installed vertically and parallel to the magnetic shielding plate.
